IMPROVEMENT IN SHUTTER-HINGES.

Specification forming part of Letters Patent No. 144.971, dated November25, 1873; application filed October 17, 1873.

To all whom it may concern:

Be it known that I, TILLIAM FOSKET,Of Meriden, in the county of NewHaven and State of Connecticut, have invented a new Improvement inShutter-Hinge and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure 1, a front view Fig. 2, a top view Fig. 3, a rear view; and, inFig. 4, a rear view in the position as when open.

This invention relates to an improvement in that class of shutter-binges which are designed to hold the shutter in an open position, andparticularly to that class in which a flange on the swinging part, whenopened, drops behind a corresponding flange on the stationary portion,and from which position it must be raised before the shutter can beclosed. This class of hinges has usually been constructed with theflange parallel to the face of the hinge and inclined upon the innersurface, so that a certain amount of power applied to the shutter wouldcause one part of the hinge to ride up one part of the other. An inclinehas been formed at the pintle for the purpose of raising the swingingportion of the hinge. In all of "these a difficulty occurs when thehinge gets slightly turned out of position, or when one part is out ofline with the other; such a con dition is unavoidable after alittle use.In

'such case the incline at the pintle is not sufficient to raise theswinging portion so that the outer end of one flange will clear theflange of the other, or the point of the flange on the swinging portionwill not readily rise up the To overcome these difliculties is theobject of my invention; and it consists in forming the loose or swingingportion of the hinge with an elongated opening for the pintle, andforming the other portion with a flange which turns at right angles ator near the extreme ends, so that when the swinging part passes over theflange it will, by the rightangled portion, be thrown transversely, theelongated opening at the pintle allowing such movement, and so that inclosing, if the shutter be forced transversely, the end of the flange onthe swinging portion of the hinge will ride up the end or right-angledflange 'clear of the locking-flange, as more fully hereinafter deangles,or nearly so, forming a flange, D, and

this is inclined uponthe inside, as seen in Fig. 3, at an angle of aboutforty-five degrees. The other leaf or portion, E E, of the hinge, whichis secured to the shutter, is formed-with an elongated opening, F, so asto set over the pintle and turn thereon, as in other hinges of thisclass. The plate E is formed with a flange, G, corresponding to theflange (J, and so that, when the hinge is open, it will drop behind theflange O. The end or nose of the flange, G, as at a, is inclinedcorresponding to the inclination of the flange D, and as the part Edrops over the flange of the part A the flange D will cause the hinge tobe thrown back upon the pintle, the elongated opening in the part Eallowing such movement; therefore, if the sh utter be pressed in theopposite direction-that is, so as to force the nose of the flange Gagainst the flange D-it will easily ride up that flange and carry theflange G above the flange C, so as to pass over and allow the shuttertobe closed.

If, as is often the case, the hinge, from use, gets turned out ofpositionsay, as denoted by the broken lines in Fig. 4-the action betweenthe flange G and the flange D will be the same, although the other endof the part E does not lie down upon the pintle.

By the employment of the flange D and the elongated opening F themeeting surfaces of the two flanges O and G may be very nearly vertical,and thus more firmly hold the shutter in an open position. By theemployment of the flange D, I am enabled 'to form a dead look by makinga portion of the flange G at the outer end vertical, as at 12, Figs. 3and 5, and a corresponding vertical portion, m, on the flange G. Thisvertical portion on the flange O is on the outer end or near the flangeD, so that, when the part E is raised to that point,

the lock becomes dead, and is only released 2. The plate A,'providedwith the pintle B, by a longitudinal movement running up the the flangesC and D, at right angles, or nearly flange D to throw the flange G fromits look so, to each other, combined with the plate E, on the flange O.elongated opening F, and fit nge G, when the I claim as my inventionsaidflanges O and G are constructed with a l. The plate A, provided with thepintle B, portion of their surfaces, 1 on, vertical, so as to the flangeG, and the flange D, at right angles, form a deadlock, substantially asdescribed.
